- lisper 9y agoWhat does it mean for TR-light to be emitted and absorbed then? Does TR-light carry positive or negative energy? Because if it carries negative energy, and it is absorbed before it is emitted, then TR-light behaves exactly the same as regular light. You've just swapped the meaning of "emitted" and "absorbed".
